Question 4 {1 point) As shown in the figure, a wire and a 10 Ohm resistor are used to form acircuit in the shape of asquare, 20 cm by 20 cm. A uniform but non steady magnetic field is directed into the plane of the circuit. The magnitude of the magnetic field is decreased from 1.50 T to 0.50 T in a time interval of 100 ms. The average induced current and its direction through the resistor, in this time interval, are 0 40 mA, from b to a. O 40 mA, from a to b O 4 mA, from a to b. O 0.4 mA, from a to b O 4 mA, from b to a
